Application filed March 20, 1908. Serial No. 422,276.

in motor supports, particularly adapted for use with playing attachments for musical instruments of the type employing an electric spring, air or other motor for driving the operating mechanisms, and the primary object of the invention is to provide an improved flexible, non-resonant support for the motor, whereby the'casing of the inciplesof this invention. Fig. 2 isa front strument will be relieved of all vibration of the motor and thehumming and buzzing of the motor will be overcome.

Affurther object is to provide an improved, simple, durable and eflicient support for suspending the motor within the casing and by means'of which the motor may be readily placed and secured in position and may 'asreadily be removed therefrom.

To the attainment of' these ends and the accomplishment of other new and'useful objects, as will appear, the'invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shownin the acc'ompa'nyihg drawings illustrating the embodiment of the invention, and in which- Figure 1 is an elevation artly in section of an improved support of this character constructed in accordance withthe prinelevation of the improved support. V Fig 3 is'a view- ,sitnilar'to Fig- 1 of a modified form of the invention. Fig. 4 is a plan view of the support shown in Fig. 3. i Referring more particularly to the drawin gs and'in the exemplification of the invention shown in Fig. 1, the numeral 10 designates a member constructed of any suitable'material, such as wood or the like, and '11 designates a flexible, non-resonant member which may be constructed of any suitable -material, such as leather or the like, and is secured by 4 one extremityto the member 10 by means 'of 'suitable fastening devices 12, such as screws or the. like. The

85 member'llfisaof'a six'itableilengthto extend beyond and depend from the member 10 and to the free extremity thereof is secured the base 13 of the motor 14, whereby the motor will be suspended by the member 11. The motor is adjustably connected in. any manner to the base 13 such as by means of an adjusting screw 13 engaging ears or projections l3 on the base, and projections 13 on the motor. The fastening devices 15 pass through the flexible member 11 and through one extremity of the base 13 so that when the support is secured to the casing 16 of the instrument, the motor will be suspended by'the non-resonant member 11 and the member 10 is of a suitable thickness to hold the member 11 and the motor base 13 spaced from the casing 16. The member 10 may be removably secured in position in any desired or suitable manner, preferably by means of fastening screws or bolts 17 which pass through the member and into the casing 16. I

A supporting rod or member 18 is secured by one extremity to the motor frame 19 preferably by means of the screw or bolt 20, which passes through an eye 21 in one extremity of the rod 18 and which bolt serves to fasten the plate 22- to the motor frame. The bar or rod 18 is ofany desired or suitable length and the free extremity thereof is preferably bent to form a hook 22 which hook is covered by a suitable non-resonant material 23, such as a rubber sleeve or the like to deaden-the noise caused by the vibration of two metallic parts on each other. This'hookshaped end is adapted to engage a suitable eye 24 which is secured into another portion 25 of the casing of the instrument, so that the rod or bar 18 will cooperate with the flexibl'e support 11 for holding the motor in position within the casing. When it is desired to remove the motor, the supports may be readily detached and when it is desired to replace the motorin the casing they may as readily be attached'to the casing. I

In the modification of the invention shown in Figs. 3 and 4 of the drawings, the

support for the non-resonant member 11 is I i in the form of a hollow frame comprising spaced side and end members 26, 27, across I which the non-resonant member 11% extends o. and is secured by its extremitiesby means of the fasteningdevices 12 to two -of the opposite members of the frame, preferably the end members 27 and the non-resonant member is of a width somewhat less than the width of the opening in the frame so that, the body portion of the member 11 is held out of engagement with the frame Work. Secured to one of the end members 27 are spaced eye-bolts 28 which are adapted to engage suitable spaced hooks 29, which latter are secured to the casing 16. The other member 27 of the supporting frame is preferably provided with an opening 36 sothat when the supporting frame 26 is held in position within the casing of the instrument by means of the eye-bolts 28 and the hooks 29, the frame may be held against displacement by means of a suitable fastening screw or bolt 31, which passes through the opening 30 and into the casing 16. The base 13 of the motor 14 is secured to the non-resonant member 11 by means of the fastening devices 15in a manner similar to that shown in Fig. 1 of the drawing and the supporting frame for; the non-resonant member is of such a size that the motor base 13 will be supported and suspended entirely by the non-resonant member 11 and held out of engagement with the frame work.

- With this improved construction of non resonant support, it will be apparent that all vibrations of the motor will be taken up by the flexible support 1111 and as that is supported out of engagement with the frame and the casing, all humming or buzzing of the motor which is present when motorsrest upon a solid base will be overcome, this improved construction at the same time permitting a slight vibratory movement of the motor. In order that the invention might be fully understood by those skilled in the art, the detailsof the foregoing embodiment thereof have been thus specifically described but What I claim as new and' desire to secure by Letters Patent is 1. A. non-resonant support for motors for.

musical instruments, consisting of a sup-,

. porting member adapted to be connected with the instrument casing, and a flexible non-resonant member secured to said .supporting member with a portion thereof out of engagement with said supporting member, and a motor secured directly to and suspended by said member out of engagement wlth the supporting member and free to transmit lateral vibrations to said flexible member.

2. In a device of the class described, a supporting member, a flexible non-resonant element secured to said supporting member with a portion thereof out of engagement with the supporting member, a motor secured-directly to said element at one side thereof and out of engagement with the supporting member, and'an independent non-- resonant" suspension device connected with the motor, said device comprising a rod connected atone end to the motor and having a hook at the other end, and a nonresonant sleeve covering the hook.

' In a device of the class described, a supporting element, a leather member secured to the element, a base supported by the leather member out of contact with the element, the base being formed with threaded lugs, an electric motor having threaded lugs, and a screw adapted to engage in the lugs to hold the motor adjustably in position.
